People generally know about pig iron. Most visitors to Beckley Furnace have seen the signs about how the furnace worked, and how it turned iron ore, charcoal, and limestone into pig iron. You may even have heard one of our hosts describe the process for you if you’ve visited when one was on duty.

However, fewer people know about slag. If you’ve ever wondered where the stuff that’s left over from the iron ore and limestone goes after the iron is made and what happens to it, then you’re asking the right question — and slag is the answer.

In this video, Christian Allyn visits the slag pile (and it is a big one!) at Beckley Furnace and shows you what you would find there if you visited yourself. And he tells you quite a bit about the stuff as well.

Thanks to Christian Allyn, our knowledgeable and personable presenter. Thanks to Eleanore Jenks who directed the video and who did the video capture as well. Between the Lakes Group is responsible for post-processing, as they call it in the video trade.
